You could easily use maximum loads published for the 9.3x57 Model 96 loads (57,000psi max) as your intermediate loads.
The 9.5's case capacity is roughly 8 to 10% larger.
In other words, start at 48gr. H4895 with a 270gr. and go from there to where you are comfortable.
You could even start with my 300gr. load of 45gr. H4895 & use a 270gr. bullet. With that, in my model 96, I got 2,170fps with the 300gr. sized down .375 Hornady RN and almost NO expansion of the web (not the base) from FL sized brass.
My mic indicated I had 1 ten-thousandth to 2 ten thousandth expansion at the web over FL sized brass. .0001" to .0002". Not 1 or 2 thou - 1 to 2 ten thousandth.
